2,791,958 REGISTER FOR PERIMETER HEATING Regner l). Schjerning, St. Vital, Manitoba, Canada Application August 27, 1954, SerialNo. 452,558 Claims. (Cl. 98-40) My invention relates to new and useful improvements in hot air registers, particularly hot air registers adapted for use in perimeter heating systems, the principal object and essence of my invention being to provide a device of the character herewithin described whereby two distinct temperature zones are provided.

A further object of my invention, in conjunction with the foregoing object, is to provide a device of the character herewithin described in which the two distinct temperature zones are formed by the provision of means whereby the air entering the base of the register is divided into two portions, the rear or higher temperature portion blanketing the wall surface and the front or slightly lower temperature air fanning outwardly into the room and causing also a recirculation of the air within the room.

Yet another object of my invention is to provide a device of the character herewithin described which is extremely simple to install, inasmuch as it is adapted to be placed on the floor against the wall.

Still another object of my invention is to provide a device of the character herewithin described which is extremely simple in construction, economical in manufacture, and otherwise well suited to the purpose for which it is designed. 7

With the foregoing objects in view, and such other objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:

Figure 1 is a front elevation of my device.

Figure 2 is a vertical side section through Figure l, but showing the device in relation to the wall and floor of the building.

Figure 3 is an underside view of my device.

Figure 4 is a fragmentary exploded view of one end of my device.

Figure 5 is a fragmentary perspective view showing the attachment of the front panel to the intermediate panel.

In the drawings like characters of reference indicate corresponding parts in the different figures.

In the field of hot air heating, increasing use is being made of the so-ealled perimeter method, whereby the hot air is fanned upwardly over the inner surface of the outer walls of the building so as to form a blanket of warm air between the cold outer wall and the rest of the room, in contrast with the conventional hot air heating, which normally is situated on the inner walls of the building with the cold air return registers adjacent the outer walls.

The register hereinafter to be described accomplishes this blanketing of the cold outer wall, as well as providing two distinct temperature zones, together with a recirculating feature whereby air is drawn from the room and mixed with some of the warm air dscharging from the register.

1: ited States Patent ice Proceeding now to describe my invention in detail, it will be seen that it comprises a substantially rectangular rear panel 1 having the side edges 2 and the top edge 3 angulated inwardly slightly as at 4 and then at right angles to the plane of the main panel as at 5. This panel is adapted to be secured to the wall 6 resting on the floor 7, the method of attachment being screws or any other conventional means (not illustrated).

Secured in spaced and parallel relationship to this rear panel is an intermediate or dividing panel 8 also of substantially rectangular configuration, but having dimensions slightly less than the rear panel 1. The side edges 9 and the top edge 10 of this panel are also angulated forwardly slightly, as illustrated. This panel is maintained in spaced and parallel relationship from the rear panel 1 by the provision of a pair of air directing vanes 11 which consist of arcuately curved strips havingattachment lugs 12 formed thereon, and it will be appreciated that if these are positioned between the panels, the aforesaid spaced relationship results. Metal screws 13 are adapted to pass through the panel 8, through the lugs 12 and into the panel 1 thus securing the intermediate panel and the vanes 11 to the rear panel in the desired relationship. j

The intermediate and rear panels 8 and 1, thus define what I call a wall blanketing chamber, which is open at the sides and top. The bases 1' and 8 of the rear and intermediate walls are also open and define an air inlet 14 which is adapted tobe situated over an opening 15 within the floor 7, which in turn communicates with a conventional hot air supply duct 16.

From the foregoing, it will be seen that hot air passing through duct 16 and indicated by the single-headed arrows 17, is divided by the intermediate plate 8 into two portions. The portion of the air passing between the intermediate plate 8 and the rear plate or panel 1 passes upwardly and is fanned outwardly on either side by means of the vanes 11 to blanket the inner surface 18 of the wall 6, as indicated by the single-headed arrows 17.

A front panel 19, also of substantially rectangular configuration, is adapted to be detachably secured to the intermediate panel 8, as will hereinafter be described. The side edges 2% and the top edge 21 of the front panel are curved inwardly or rearwardly, as clearly illustrated, and are provided with channels 22 securing the front panel to the intermediate panel so that the major portion 24 thereof is in spaced and parallel relationship to the panel 8.

A plurality of substantially rectangular slots are formed through the curved side and top edges of the front panel so that the other portion of the air passing from duct 16 can exit into the room. The front and intermediate panels thus assembled define what I call a recirculating air chamber 25 and the position and configuration of the slots 20' in the front panel causes this air to fan outwardly, upwardly and forwardly, as indicated by the double-headed arrows 26.

The bases 8 and 19 of the intermediate and front panels respectively also define an air inlet and spans the opening 15 within the floor, as clearly shown in Figure 2.

Adjacent the base 19 of the front panel, I have provided what I define as a recirculating air inlet 27, which consists of an inwardly projecting flange 28, the upper edge 29 of which is spaced from the upper edge 30 of the inlet. This inlet communicates with the room air and the upwardly flowing air from duct 16 therefore induces the room air to enter through this inlet, as indicated by the double-headed arrow 26. This air recirculating from the room and mixing with the hot air passing between the front and intermediate plates lowers the temperature of the air in this chamber and thus causes a slightly lower temperature zone forwardly of the air blanketing the wall.

This assists in more even heating of the room, particularly in view of the recirculating aspect-of the device and has been found to provide a more even temperature over the entire room than the conventional perimeter heating register.

Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
